013 WAYNESBORO, PENNSYLVANIA, A CORPORATION CAN FILLER I Application filed December 27, 1927. Serial No. 242,766.

M invention relates to can fillers and more speclfically to devices used in filling the cans in which the blocks of ice are frozen in'ice making plants. Itis an object of the invention to provide a filler which will operate to fill each can with the same amount of water so that the blocks of ice will all freeze in the same length of time and will be of the same size. I

has been employed in which the quantity of water was regulated by a float in the tank;

These floats were not accurate so that the quantity of water supplied 'to the several ice 1 cans was notconstant. In my invention a positive quantity of water is delivered each time the tanks are emptied for the tanks are filled each time. An air vent in the top of'the tank provides means of esca 'e forthe airas the tank fills but is closed y a float valve when the water fills the tank. The volume of water supplied by a tank is varied byvarying the volumetric size of displacing means within the tank itself. V

Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate'similar parts; V

Figure 1 1s a perspective slde view of a fill- Figure 2 is a perspective front view showing a plurality of tanks. Figure is a sectional viewthrough the tank showing the valve and theinterior of the tank.

Figure 4 is adetail view of the valve.

In the drawings numeral 10 indicates in general'outl'me a tank used'in myinventions This tank consists of a cylindrical wall '11 and 40 upper and lower ends 12 and 13. The upper '45 holding the valve bodyl17 which is screw threaded therethrough.- 'The valve body is provided with a float valve 18 held from dropping off its seat by a bar 19 attached to members 20 on the valve seat. The valve 18 is preferably of cork'or any other substance In can fillers heretofore in usean open tankwhich will float upon the surface of the Water and at the same time seat so asto prevent the escape of water when the water reaches the top of the tank.

The lower end 13 of the tank 10 isperforated at21. :This port is connected with a valve casing 22 to which are connected suitable inlet and outlet pipes for the admission and exhaust of fluid into and from the tank as will be more fully explained. I I v p The valve housing 22 has a flange 23 which is suitably secured to the bottom 13 of the tank. A pipe 24 leads from the valve casing to the point to which the fluid is to be delivered; The inlet port 25 of the valve casing is connected to a fluid manifold inlet pipe 26. A check valve 27 provides for admission of fluid to thetank but prevents its return to the pipe 26. A valve 28 controls inlet for fluid to the pipe 26. v V 7 .As shown in Fig. 4, the valve casing 2 2 has a spring seated valve 29 therein. This valve is adapted to seat on the seat 30 and is held thereon by compression spring 31held between the disk 32 on-the valve and theend cover 33 of the valve casing. A bellows. 34 surrounds the compression spring31 and is securely fastened to the disk 32and to the end cover 33. This bellows prevents the fluid in the tank from acting against the disk 32 and thus relieves the pressureon the outer surface of the disk 32 and hence gives a bal anced valve which may more easily be lifted from its seat. An eye screw 35 is fastened'in the valve 29. A rod or link 36 passes out through the end cover 33 and provides means for manually lifting the valve from its seat.

This is done in thefollowing manner Arock;

shaft 37 has arms 38-and 39 thereon. .A link 40 connects the arm 38 withthe link 36. g A similar link 41 connect's'the arm39 with the valve stem 42 on the inlet valve'28. 1 This latter valve is similar in structure to the outlet valve just described. f l Q Therock shaft 37 has an arm .43 to which is pivotally. connected a lever 44 at 45. The lever 44 has lugs 46 and 471 on the lower side for-engaging a catch-to hold the lever inpositiontoholdthe valves in open or closed position as desired. When in the position MM t shown in Fig. 1, the inlet valve 28 is open and the exhaust valve is closed. When the lever 44 is pushed to the right the arms 38 and 39 will rock to close the inlet valve and open the exhaust valve. The bellows prevents the head of fluid in the, xerting its pressure againstlthevalve andiso renders the operation of these valves relatively easy.

the tank and attached to the side theieehs a pan flf unis anhas an -L-shaped pipe 49'extending salads upward as shown in Fi 3. The L-shaped pipe 49 enters the end 0 the pan 48 through opening 50. This elbow is not rigidly attached to the pan 48 butis so inserted asto altcw' the elbow rto, be turned down so as to bning thewnpper send 51 below the top of the 'nmtoahringit to any level desired.

Floats were unreliable an would not deliver a constant volume. With my device the float has been abolished and a positive volume which is always constant is delivered at each filling operation. The volume also may be regulated with very nice precision so as to: suit cans of any capacity. The balanced valves provide ease oiqoperationl a It will be appreciatemiuuthermore, that the whole assembly-is relatively simple and has every few parts to get outlet order and the parts furthermore are easily accessible and removable in case they do get out of order for any reason.

' It will be obvious to those skilledin the art.

that various changesmay. bemade, in my devicewithout departing fromthe p rit of he invention, and I, therefore, do not limit my self to what is shown in, the drawings and described in the specification, hut only as set forth in the appended claims, c

Having thus fully-described my said invention, what I claim as new and desire to secure by Letters Patent, is; 1. Acanfilling devise comprising a tank, mlet and outlet ports .to and from said tank, a flllld container mounted withinsaid tank and adaptedtobefilled with liquid as the tank is filled and to retain the same when the tank is 'em tied, and means for varying the capacity'v-o the said container, substantially as set forth I a 2. A oan filling device comprising a tank, inlet and outlet ports to and from said tank, a vessel mounted within said tankhaving a pipe in communication with its interior and xtending through one side and normally bent upward but tiltable to any \predeten mined angle from verticahthe said vessel bemg adapted to fillwith liquid as thetank fills and to retain the liquid as the tank empties, whereby the eflective volume of liquid dis-- p sed. from the vitank islessened bythe volume of thesaid YBSSGL'th said 'pi e being tiltable *to vary the displacement of t e vessel from zero to its maximum volume when filled with liquid, substantiall as set forth. In witness whereofi have hereunto set my hand at Waynesbono Pennsylvania, this twentieth day of Decsm r, Ar D. nineteen hundred andtwenty-seven'.
